  • What would cause a single working website to not work on 1 out of 5 devices on a network?

    - by th3dude
    There is a specific website that loads up without problem on all machines on my network (both wired and wireless) except one laptop. This laptop is a Windows 7 machine that was just recovered using the recovery partition, so it is fresh. The site will not load in Firefox 3.6 or IE 8. The website is http://www.weightwacthers.com The site loads fine on my desktop, iPhone, and Droid, but not the laptop. In all my years in this business I've honestly never seen this happen. Also, 'Is it down for me or everyone' reports that it is indeed only me. What would cause this to happen?

  • How can I use my Windows 7 computer to share WiFi connection with PCs that don't have wireless?

    - by Tom Auger
    Long story short: modem and wireless router are downstairs and we're having a LAN party where some visitors don't have wireless. There's no way to run the length of cabling required, so looking for options. My Windows 7 Home Premium PC has a wireless-n connection, and I'd like to see if I can use it as a "hub" or switch of sorts, running an ethernet cable out of the back and into a switch, then splitting off to the other PCs. Is this an option? I know with Internet sharing, you can set up your PC as a wireless access point, but I want to do the opposite.

  • Access server by hostname without domain

    - by projectshave
    I want to access services on other machines on my home network with just their hostname. In every browser, "http://machine" fails, but adding a period in "http://machine./" works. Is there a way to avoid adding that extra period? My setup is a router with DD-WRT w/ DNSmasq turned on, Win7 machines and several Ubuntu VMs. nslookup works fine with just hostname. Remote desktop works, but TightVNC needs the extra period. ssh needs the period. As I said, all my browsers need the extra period. I'd prefer a solution that doesn't require manually maintaining the hosts file. Thanks.

  • Is it possible to restrict the connection duration per client on the router (say with OpenWRT)?

    - by static
    How to limit the connection duration per client per period (say, one MAC-address can connect only for 3 hours per week to the network). Where could be defined such a rule? In the firewall? So the rule should define not statically times (this is simple), when the client is allowed to access the network, but the duration of the connection per day/week/month, etc. How/where to implement such rules? Is it possible to do so with OpenWRT/DD-WRT?

  • lan extension over wide area

    - by avinash
    when we use technology like leased line to extend a lan over a wide area(like when connecting two offices such that hosts in both offices use private ip addresses) , why do we use encapsulations like ppp or hdlc...what can't we use the ethernet header to communicate because mac addresses are unique and can easily be used to identify hosts just like a small area lan... this question may seem a bit absurd but it has been bugging me...so plz explain

  • Why would one server be sending DUP ACK packets to one PC, which is responding with HTTP RST packets?

    - by IronicMuffin
    I'm not a network profressional, so please excuse any wrong language. I was debugging why my DNS traffic was a constant 160Kbps on our corporate network. I opened up a wireshark trace, and I see one PC of a coworker broadcasting HTTP [RST] packets to one of our DMZ servers at the rate of 1000 a second. He restarted his machine, and as soon as it went offline, the server started broadcasting [DUP] [ACK] packets, until he came back online. It then resumed the HTTP [RST] packets. Apparently this server has been doing this kind of behavior since it went live. I believe it did this with a printer and an access point as well. Can anyone explain why this behavior is occurring? Any solutions? The initial research was done because there have been "bandwidth issues" and I wonder if this is contributing.

  • iPhone 3G can't see any WiFi networks, ever

    - by torbengb
    I've got WiFi turned on in the settings, and ask before connect turned off. My iPhone 3G should see several WiFi networks, but it lists none. It also does not list my own network, which my computers see just fine. It has worked earlier but stopped working recently (possibly because of or at the same time of other trouble (which a restore solved)). The iPhone is not jailbroken. The SSID is not hidden, uses WPA2. It also finds no WiFi networks when I'm at a friend's house. His iPhone 2G sees several WiFi networks, including his own. When I use the manual entry method, specifying my home SSID and the proper WPA2 passkey, then click join, the iPhone says couldn't find that network. Same at my friend's place, with his SSID and passkey. I've just backed up my iPhone, then restored it, to see if refreshing the firmware would help. It didn't change anything. Is my iPhone broken? How can I fix this?

  • Spare PC with XP to be used as Torrent Downloader and local Web Server HOWTO?

    - by gslide
    Hi I'm a bit in a pickle in trying to setup my old laptop using Windows XP to be able to serve as two devices in one, I want to make it a downloader for torrents and a local web server as well and how to do this? I have a wireless NIC and LAN, and I have two internet connections and i would like to be able to download torrent only on LAN and be a webserver on the Wireless, also the webserver can be accessed through the internet. The reason for trying to separate the connection is I can't have torrent downloads using all my bandwidth as my web pages cant be access as it times out or too slow. I have two broadband connections, is this even possible or would i need a different OS or program that I can download? please

  • Cannot enable wireless Ubuntu 10.04

    - by woaddoa
    I have recently installed Ubuntu 10.04, however I am having trouble getting wireless to work. Ubuntu says that wireless is disabled, and I am unable to enable it. I have tried Administration Hardware Drivers however the only drivers listed are Nivida graphics ones. I am unsure what to do as I do not think the process is the same as searching for drivers for a windows machine. Any advice appreciated.

  • LMDE detects a wireless card, but can't use it

    - by Davidos
    LMDE can see my wireless card, and correctly identifies it, but it refuses to let me turn it on through the shiny graphical interface. Is there a way to use the non-shiny terminal to turn on my wireless? One small tidbit I noticed was the stated version; it says the version is 00. I believe that's hexadecimal for 0, which may indicate something screwy with the software. It would be nice if someone could tell me how to figure out how to solve this kind of problem in the future. *-network DISABLED description: Wireless interface product: Centrino Wireless-N 1000 vendor: Intel Corporation physical id: 0 bus info: pci@0000:09:00.0 logical name: wlan0 version: 00 serial: 91:e3:7b:0d:a3:a9 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlagn driverversion=3.0.0-1-amd64 firmware=39.31.5.1 build 35138 latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:43 memory:e1d00000-e1d01fff I've tested multiple other network managers, and none of them work.

  • How do I fully share a Hard Drive on my Local Network?

    - by GingerLee
    I have 4 computers connected to a router (DD-WRT) My main PC is Windows 7 (Home Premium). This machine has 2 Hard Disks: HD1 is used for my OS and the other (HD2) is used to store files. My 3 other machines are 1. Ubuntu Destop that I use to learn about linux, 2. A Mac OSX laptop, and 3. A netbook running windows 7. How do I easily share HD2 with my other machines? I would like all my machines to have full access & permissions to HD2 however I would like to RESTRICT access to only PCs that are connected to my router (either via LAN and WiFi) --- btw, I know this is not very secure due to WiFi vulnerability , however, I currently MAC address restrict WiFi connections my router. Extra Info: I have already tried to use the Windows Folder Sharing feature: i.e. I right click over the icon of HD2, and click on the Sharing Tab, but in sub-window labeled "Network File and Folder Sharing", the "Share" button is grayed out. I can click on "Advanced Shared" but that just takes me to a screen in which I have to set certain permissions. What is not clear to me is: How do I set a criteria that shares HD2 with all computer connected to my router?

  • Network-related icons suddenly removed

    - by Velcro
    Hello, On a fresh Windows 7 installation, I created some shortcuts icons to network shares on the Desktop. Without any warning, these icons are sometimes and randomly deleted from Desktop. I totally don't understand what it happens! They are not hidden, they just are simply deleted. This behavior occurs on one computer in my company. Others Windows 7 computers are not affected by that. And also it's the first time I encounter that. Do you have an idea about this problem? Thanks.

  • What is the network address (x.x.x.0) used for?

    - by Shtééf
    It appears to be common practice to not use the first address in a subnet, that is the IP 192.168.0.0/24, or a more exotic example would be 172.20.20.64/29. The ipcalc tool I frequently use follows the same practice: $ ipcalc -n -b 172.20.20.64/29 Address: 172.20.20.64 Netmask: 255.255.255.248 = 29 Wildcard: 0.0.0.7 => Network: 172.20.20.64/29 HostMin: 172.20.20.65 HostMax: 172.20.20.70 Broadcast: 172.20.20.71 Hosts/Net: 6 Class B, Private Internet But why is that HostMin is not simply 64 in this case? The 64 address is a valid address, right? And whatever the answer, does the same apply to IPv6? Perhaps slightly related: it also appears possible to use a TCP port 0 and an UDP port 0. Are these valid or used anywhere?

  • Monitoring/logging a malfunctioning internet connection

    - by Pekka
    I have a mysterious internet connection problem: Every 15-20 minutes, the connection will become very slow, and take 2-3 minutes for anything to load. I've had a technician from the ISP over here to test the hardware, and everything is in pristine condition. They have no other explanation than a configuration error on my machine, a possibility I can exclude 90% because I'm experiencing the same problems with another machine. I will have to monitor the situation now, and I would like to run a program that logs when internet connections become slow. I thought about putting something together using at and wget. Does anybody know of some other tool for this that does this out of the box - maybe something with an adjustable request frequency, logging connection speeds etc.?

  • How does a frame retrieve the recipient's MAC address?

    - by Sarmen B.
    I am studying a Network+ book named All-in-one CompTia Network+ by Mike Meyers. In chapter 2 he talks about frames and how he represents them as canisters and the data within the frame contains the recipients mac address, senders mac address, data, and sequence number. What I don't understand is if the sender is sending a file via the network to the recipient, and this frame contains this data, how does the frame know what the recipients MAC address is before sending it? In regards to TCP/IP when it contains the recipients IP address, that's understandable how it retrieves that value. But I don't understand how it can retrieve the MAC address, because if that frame comes from the senders computer, goes into the router and copies itself to each and every computer that exists on the network, how did it have the MAC address to know where to go? Let me know if I'm not making sense.

  • Clients can make maximum only 15 connections to ubuntu custom server

    - by gtan
    I have a custom server in C# being run on Ubuntu 9 under mono. I can make up to 15 silverlight clients connect to the server. When I make the 16th, it just waits. And if I close one of the established connections, the 16th client is able to connect. I am making the connections from one machine. I am also not exceeding any file handle limit. The limit is 1024 and I am having around 300. Any ideas how to make more connections? Also why the number 15? Is it something linux-specific? EDIT: I have run the same server on an Ubuntu 11.10 virtual machine and was able to make more than 15 connections. I presume it's a configuration problem on the Ubuntu 9 machine then. Any help on that?

  • Website ocasionally does not load on first click

    - by tfe
    Today I noticed that my website hosted on a virtual server ocasionally does not load on first click. I click on some link, browser starts loading page but nothing loads and does not not appear any error message (like "connection reset by peer etc). Nothing. When I click the same link again, page loads immediately. The same situation on 2 computers in different browsers. It happends not always, maybe on each 20... or 30 click. Sites from other servers load without this problem. Any ideas what can cause this problem?

  • Override my ISP's "domain not found" page?

    - by Amanda
    If I screw up typing a URL, my ISP shoots me over to their branded search page. So if I type "superuser" in my location bar I end up at http://domainnotfound.optimum.net/cablevassist/dnsassist/main/?domain=superuser I'd like my browser to leave the location the way it was and just say "nothing doing," rather than redirecting me to a search. Can I override that in my own /etc/hosts or at my router?

  • Windows-7 Ultimate 64 bit wont connect to my wired/wireless networks

    - by A302
    Windows 7 Ultimate 64 bit. Everything was working fine & then just stopped working. The nic card Realtek PCIe GBE Family Controller is enabled but does not connect to my router (cables & router ports are good). Wireless Atheros AR5007EG is enabled but the connection is limited (encryption type / key have been verified). A laptop running XP can connect both wired / wireless. SSID is not being broadcast, connect to network if it is not broadcasting is checked. Have checked services.msc for Bonjour & did not see it listed. Network & sharing center does not list any active networks. Device manager lists both devices as functioning properly. Router configuration has not been changed. Virus scan has not found anything. I would like to fix this rather than using Acronis to do a system restore. Thanks in advance for any advice offered in solving this. 26 Jan, the nic card & wireless are working using PCLinux OS Live CD. It appears that the problem is Windows 7 related.

More generally - what is an correct algorithm to compute the number of available subnetworks for the same mask?
